I don't really know how to discuss this in real life, partly because I know I am an awful person.
My DH is an amazing man, he truly is and I am very lucky to have him. There are a couple of things that are on my mind and it isn't going away. Basically, the sex is rubbish and I don't fancy him as much as I used to due to his weight again. I used to be a sexual person before him, but he has killed my sex drive (we have been together 12 years). I have tried to talk to him (it hurt his feelings, and I was gentle about it) and tried to initiate new things but it just isn't working.
Quite a lot lately, and it is increasing - I find myself day dreaming about having sex with other men. One night out with friends I was propositioned and I didn't act on it - but I really wanted to! I adore DH, despite what I have written here, but the thought of being with him for the rest of my life (and I want to be) with rubbish/no sex is so depressing. I feel so rubbish, and I guess I deserve to for thinking like this. I don't know what to do really
